Find LCM of 902,816,855,144 with Prime Factorization
| 2 | 902, 816, 855, 144 |
| 2 | 451, 408, 855, 72 |
| 2 | 451, 204, 855, 36 |
| 2 | 451, 102, 855, 18 |
| 3 | 451, 51, 855, 9 |
| 3 | 451, 17, 285, 3 |
| 451, 17, 95, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 451 x 17 x 95 x 1 = 104884560
Therefore, the lowest common multiple of 902,816,855,144 is 104884560.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
902 x 816 x 855 x 144 = 90620259840
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
902 : 1, 2, 11, 22, 41, 82, 451, 902
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,816,855,144, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
816:2x 2x 2x 2x 3x 17
855:3x 3x 5x 19
144:2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 90620259840/(1x864)
LCM = 90620259840/864
LCM = 104884560
Thus, we can understand that the LCM of 902,816,855,144 is 104884560.
